dailytech.com — In an interview with Mark Bohr, Dailytech squeezed a few more details about the 45nm Penryn processor. Of particular interest, the new CPU will use SSE4, uses a different gate technology and works in existing motherboards.

@warriorscotYou key problem is "if they release processors that perform equally well", AMD is now behind intel, not far behind but it will be soon. And i don't mean technologically, i mean in fabrication. If you have two chips that perform equally well, one at 65nm and one at 45nm the 45nm uses less power and can be clocked faster.AMD so far, even in their latest 4x4 hasn't really held a candel to intel, (read the lackluster reviews of 4x4), it's always been true that AMD has had better memory access, and thus needed less cache...and thus had cheaper components. It doesn't however adopt new technologies quickly, (like DDR2) etc.If you really read up on the 2 companies long term developement plans, AMD doesn't come close to what intel is "trying to do", intel is trying to get down to 22nm, 1 billion transistors, 8 cores+, (eventually an integrated memory controller), DDR3, PCIe 2.0. (all by 2010 (or so) no less) Even if they perform the same clock for clock, while newer technologies are expensive, that doesn't matter in the long run, intel has the advantage.

@maninblac1: Do you know if the Dell XPS700 series has a "quality" motherboard? I've been eyeing their C2D systems in the business outlet (some are selling for cheaper than the component parts and are decent machines) and wondered if they would also allow these new chips.

@dumbledoritoif i recall the XPS700 had a foxconn motherboard in it, (obviously dell rebranded).But here's a link to a site that discusses the XPS700's ability to use newer processors, it more primarily concerned about quad core, but don't expect your board to run a fab shrink if it doesn't support the quad core signal specs.<a class="user" href="http://direct2dell.com/one2one/archive/2006/11/15/3573.aspx">http://direct2dell.com/one2one/archive/2006/11/15/3573.aspx</a>It appears that dell will leave you out in the cold, no bios updates, no support....nothing. Bear that in mind.

"meaning existing motherboards can physically harbor the new CPU but electrically might not."Shame motherboard developers like to take shortcuts and develope their products so that they ride the edge of the specs of chips (and thusly can use cheaper voltage regulators, or underdesign the board's electrical pathways to be tolerant to certain kinds of noises)."Presumably that just means a BIOS update? If they physically fit in and the mother boards have the bandwidth etc, I'd have thought motherboard manufacturers could release updates if they can be bothered."Presumably, yes. But in actuality about 1 in every 4 boards just isn't going to work because of spec-bending. The big-names usually get it right (and the motherboard in your Dell is probably made by one of those big names so it should be okay), but some of the smaller motherboard manufacturers, or even some of the bigger manufacturer's cheap-o lines just don't cut the mustard.

Who buys intel motherboard?
lucid270Jan 27, 2007
well.. it is a die shrink, not a completely new architecture

so when can we expect this to come out?
